Abstract

A method for scheduling cyclic control applications on a controller includes defining a plurality of function block clusters by clustering a plurality of function blocks of the cyclic control applications based on a sampling time of each function block, creating a plurality of organization blocks from the plurality of function block clusters, each organization block comprising at least one function block from a function block cluster and an organization block record including a sampling time value and next deadline time value associated with the corresponding organization block, and scheduling the plurality of organization blocks for execution on the controller, based on either a sampling time value and/or the next deadline time value, where a sampling time value of an organization block is based at least one sampling time of at least one function block of the corresponding organization block.
